ygrophorus olivaceoalbus is a rather common and widespread edible ectomycorrhizal mushroom in northern Europe and North America. There is no evidence of decline. It can be locally abundant where suitable habitat exists. Therefore, it is assessed as Least Concern (LC).
Why suggested for a Global Red List Assessment?
Hygrophorus olivaceoalbus is widespread in Europe and North America. Common in the northern parts, less so to the central and southern parts. The area of occupancy (AOO) of this species is much larger than 2,000 km², and its extent of occurrence (EOO) is much larger than 20,000 km².
Population and Trends
The population size is likely to be very large since this is such a widespread species and more or less stable. There is no indication of any decline.
Habitat and Ecology
Hygrophorus olivaceoalbus forms mycorrhizae with conifers. In Europe, especially with Picea on acid, mossy ground. In the West Coast of the United States, associations are most common with Sitka spruces and giant redwoods. In the Rocky Mountains it associates with Engelmann spruce and blue spruce, and in northeast North America with hemlocks.
